    I will be and am I the Process of the Same Deal!
    I will give you a Little Info that i have Found out?
    E-85 has a 1.4-1 Ratio from gas.
    Alcohol has about 1.7-1.
    E85 =80,000 BTU per Gallon.
    93 Octane =112,000 BTU per gallon
    I dont have the BTU's on Alcohol,BUT I'm sure Zipper will pop in with the Missing Info?
    In other Words,if your Alky tune is on?You will be about 15 to 20% Rich,give or take?
    e85 is Equivilant to 105 Motor Octane,and have talked to guys with over 14.1 compression,with NO Issues!
    My set-up will be 8.5 1,with a 8/71 and a Hilborn 4-Port Bug with hat Nozzles and Port Nozzles.I will be using a 990 Enderle Pump.
    I will set down SOON and figure out what Nozzles sizes and the Split?
    Not alot of INFO for you but hang in there,more info will Pop up?

    I don't know if this will help but below is a chart on the most effecient burn ratio, of most fuels. by comparing the ratios i think you can run the same nozzles, because there's only 25% difference in alcohol and E85, but looks like you'll have jet up on the bypass pill, because it will require less fuel for the E85.
